BTB Buzz

yesterday at band practice my BTB started buzzing like a bitch whenever i took my hands of the strings (the buzzing went away again whenever i touched the strings or any of the hardware [bridge, tuners, dials] )

I definately think that you have a grounding problem. that's what my local guitar shop guy told me my problem was, and I had the exact symptoms you do... odd thing is, that it just went away over time. You may want to try to get it fixed since you're in a live environment though.

right, so i finally open it up and . . . either the wiring has been changed or the diagram on the ibanez site is out of date

There are a couple solder spots on a couple of the pot casings that look like they used to have something connected but now have another point connected to the casing of the pots instead

Also, the ground wire only seems to go from the disc on the mid pot (stacked) to the volume pot, then to the jack, there is also a thick, unshielded wrap of cable (as in, not even a plastic covering) going into the body of the bass, i dont know what it is, it doesnt seem to be on the wiring diagram but i assume it attaches to the bridge

I had some strange problems with both basses humming when plugged into my BXR amp and/or into the Sansamp BDDI and itno FOH at church. With fingers on strings, no hum, fingers off strings - a hum. Ground lift helped reduce hum.

At other gigs, sometimes a hum, other times not.

I got a new Eden WT550 the other day, tried both basses - no hum.

So, for me, it was the system rather than my bass, however there doesn't seem to be a way those monorail bridges are earthed - you'd have to earth each one separately.

Strange why your wiring doesn't match that of the official diagramme - was your bass new when you got it?

Hey Mo- congrats on the WT 550-I've been hanging out here a lot lately if I'm on line (which isn't very much)too busy practicing and having fun...Have fun with your Eden-they are a blast!...Peace...Russ.

My blues buddy from Iowa - how are ya? - wondered why I hadn't seen you much on AB.

That WT550 is just the cat's pajamas - such a beautiful amp in many ways. I'm building a couple of Bill FitzMaurice cabs to go with it as well.
